LinkedIn: No Real-Time Data Center Backup?
The business networking site LinkedIn announced plans yesterday for an initial public offering in which it hopes to raise at least $175 million. The company’s SEC filingcontained an interesting tidbit: LinkedIn said it currently has no real-time backup data center, meaning a failure of its primary data center would knock its LinkedIn.com site offline. “We recently implemented a disaster recovery program, which allows us to move production to a back-up data center in the event of a catastrophe,” The company said in its SEC filing. “Although this program is functional, it does not yet provide a real-time back-up data center, so if our primary data center shuts down, there will be a period of time that the website will remain shut down while the transition to the back-up data center takes place.” Data Backed Up, But Recovery Not Instant Is this problematic? The company says some of its key infrastructure is located in San Francisco and southern California, which are both Read more...
SSDs vs. Disks: Which Are More Reliable?
Robin Harris is an analyst who tracks emerging IT technologies and writes about the storage sector at Storage Mojo and Storage Bits. Solid-state drives are often marketed as being more reliable than hard drives. But some evidence suggests that isn’t always true. How much more reliable than hard drives can SSD’s really be? A retailer of SSDs and hard drives published its return data last month. Some of the 1 TB hard drives were more reliable than some of the SSDs. And when you consider the much larger number of bits on each hard drive, the per-bit reliability looks even better. Why do hard drives fail? Google’s study of hard drive failures – see Google’s disk failure experience andEverything you know about disks is wrong – found that 36 percent of failed hard drives did not exhibit a single SMART monitored failure. Why? Because drive failures have two components: mechanical and electrical. Hard drives are mechanical devices. Over time components wear: platters start Read more...

Google’s Data Center Spending Soars
Google’s data center spending soared in the third quarter of 2010, as the company reported capital expenditures of $757 million, the second-highest quarterly total in the company’s history. The only precedent for these spending levels is the first quarter of 2008, when Google (GOOG) was building three major data center projects in the U.S. Google throttled back its capital spending after the economic meltdown gripped Wall Street in the third quarter of 2008. In 2009 the company’s quarterly CapEx spending ranged between $139 million and $263 per quarter. Google’s data center investment began to rise in the second quarter, when it spend $476 million on infrastructure. The change in course can be clearly seen in this chart of Google’s historic capital expenditures: 1Q 2006: $345 million 2Q 2006: $699 million 3Q 2006: $492 million 4Q 2006: $367 million 1Q 2007: $597 million 2Q 2007: $575 million 3Q 2007: $553 million 4Q 2007: $678 million 1Q 2008: $842 million 2Q 2008: Read more...
October 2010 Web Server Survey
In the October 2010 survey we received responses from 232,839,963 sites. Again this month Apache increased its market share by approximately 1 percentage point, gaining 5.5M hostnames, while Microsoft and Google lost 1.3M and 400k hostnames respectively. Microsoft's losses in Active Sites were much smaller, at just over 100k, while Google lost 150k. While the other servers' gains were down this month, nginx saw a 1.4M increase in hostnames, bringing its market share up by nearly 0.5 percentage points. Notable growth includes a 400k increase in Moldova and a 700k increase in the US, which includes a 150k jump at BurstNet, a 200k jump at Hurricane Electric and an increase of nearly 400k at ServePath, LLC.

Google Data Centers used to save energy and lives
Google's official blog shares a vision to use Google's data centers to save energy and lives. What we’re driving at 10/09/2010 12:00:00 PM Larry and Sergey founded Google because they wanted to help solve really big problems using technology. And one of the big problems we’re working on today is car safety and efficiency. Our goal is to help prevent traffic accidents, free up people’s time and reduce carbon emissions by fundamentally changing car use. Data Centers are key. This is all made possible by Google’s data centers, which can process the enormous amounts of information gathered by our cars when mapping their terrain. Enabling a bunch of smart people. To develop this technology, we gathered some of the very best engineers from the DARPA Challenges, a series of autonomous vehicle races organized by the U.S. Government. Chris Urmson was the technical team leader of the CMU team that won the 2007 Urban Challenge. Mike Montemerlo was the software lead for the Stanford Read more...
